Insulators are special insulation controls that can play an important role in overhead transmission lines. In the early years, insulators were mostly used on utility poles, and gradually developed into a high-voltage wire connection tower with many disc-shaped insulators hanging on one end. It is used to increase the creepage distance, usually made of glass or ceramics, and is called an insulator. Insulators should not fail due to various electromechanical stresses caused by changes in the environment and electrical load conditions, otherwise the insulator will not play a significant role and will impair the service and operating life of the entire line.
